How are pull-ups and chin-ups different?
The most glaring difference between pull-ups and chin-ups is that you perform pull-ups by holding onto the bar with the palms of your hands facing away from the front of your body, while you perform chin-ups by holding onto the bar with the palms of your hands facing toward the front of your body. Also, while pull-ups can be performed with your hands close together (approximately shoulder width) or far apart, chin-ups are generally executed with your hands close together.
